Rotational Breeding Guide

For breeders the rotational breeding system promoted by Mr. Shogo Takrda is a great tool to use. The system is used to create well balanced cattle that do well in the cow herd and also, deliver the best overall profitability.

As a point of reference, the following major strains and sub strains of Japanese Black Wagyu commonly have these traits respective to them:

For your information a list of the highest ranking (for Marbling only) 30 sires as presented in the 2014 Wagyu Sire Summary, as calculated by Colorado State University.

The chart below compares the USDA scale to the Japanese scale.

EPD’s are the best estimates that we have of an animal’s genetic potential. These estimates take into consideration all information that is available for an animal.
The attached table gives EPD’s for several carcass and growth traits for a number
of Wagyu sires in the United States. All of the information in this summary is based on measurements from half blood Wagyu animals. These animals were raised in contemporary groups (CG’s). A contemporary group consists of animals
raised under the same management conditions. The number of progeny and number of contemporary groups for each sire are listed in the summary tables for each trait.

EPD’s are not true values, but predictions and we expect them to change with new information. The reliability of an EPD is
indicated by its accuracy (ACC), which is reported as a decimal number ranging from 0 to 1. Accuracy values closer to one
indicate that the change in the EPD will be small. When the accuracy is closer to zero, a larger change is expected. Accuracy
increases as the number of progeny and contemporary groups increases.
